ATI 916195A

The ATI Super Pulley is designed to eliminate blower belt failure. This unique supercharger Super Pulley allows your supercharger to "freewheel" when the throttle is closed. It's ideal for both competition and street applications. This pulley will fit F1/F2/F3 and Reverse rotation Pro Chargers, or any other style of Supercharger with .8750" or .9911" input shaft sizes. Current production is for 8mm HTD style belts up to 70mm wide. The Super Pulley is available in 45 teeth x 75mm wide configuration.

The Super Pulley uses ATI's Superior Sprag Technology™ to release the blower whenever it is spinning faster than engine RPM. This virtually eliminates belt failures when the car is pedaled at the drag strip. Also look for more boost between shifts, as the blower will not ramp down as fast as the engine during the gear change. Finally, the pulley will also reduce wear on your Supercharger by not allowing the gear drive to mesh in the opposite direction when spinning down.
